Create comprehensive Grafana dashboard for API latency monitoring with: - p50/p95/p99 stat panels and time series for all endpoints - Per-endpoint latency breakdown with route/method template variables - Top 10 slowest endpoints table and bar chart (by p99) - Request rate (by method) and error rate (4xx/5xx) panels - Error rate percentage (5xx/total) with SLO threshold - Latency heatmap and histogram distribution panels Add Prometheus alerting rules: - ApiLatencyP99High: p99 > 1s for 5m (warning) - ApiEndpointLatencyP99High: per-endpoint p99 > 2s (warning) - ApiLatencyP99Critical: p99 > 3s for 3m (critical/SLO breach) - ApiErrorRate5xxHigh: 5xx rate > 1% for 5m (warning) Fix api-overview.json using wrong metric name (http_request_duration_seconds → goodgo_api_request_duration_seconds).
